Magnetomechanical system for reduction the recoil of a gun

ABSTRACT

This invention is referred to the creation of a megnetomechanical or mechanical system of the recoil&#39;s reduction and hence of the gun-barrel&#39;s rebound reduction during the shooting time. This system is composed from the successive recoil springs ( 5 ) and ( 2 ) in cooperation with the cylinder ( 1 ), from a magnet (M), which pulls, on the one hand, the gun&#39;s slide (K), and on the other hand, to the cylinder ( 1 ) a reverse this time retrogression of these two retrogressive components, and from the recoil spring ( 3 ), which because of its position and size, operates as an inertia mechanism of the recoil&#39;s quick execution and reduction.

The invention is referred to a magnetic-mechanic system of the recoil'spower reduction, which is developed during the shooting time in a gun.The gun, as a mechanical system and as long a fired bullet crosses in itthe distance from the gun-barrel's chamber till the gun-barrel's muzzle,functions as a system reaction like the motors reaction. But except fromthe gun's recoiled phenomenon because of the bullet's loadinginstantaneous firing in the chamber, the provoked explosion gives to thegun's frame an instantaneous dynamical energy, annihilating any inertiaphenomenon, which was prevailing in the reference system between the gunand the user before the explosion.

In order to avoid the recoil phenomenon, the current technology ofportable guns like the revolvers, automated pistols, submachine-gunsand/or other heavy armor of which guns, the recoil systems bring in mostcases an absorption spring, and in order to increase the gun—userreference system's inertia, they use different technical solutions,which nevertheless are restricted to small improvements in the presentcase, like:

-   -   1. Through the addition of a mercury bag to the gun's front        section in order to cause vertical resultant, in order to        increase the gun's inertia during the gun-barrel's rebound.    -   2. Through the gas escape from the gun-barrel's upper section        with momentum and direction reverse of the gun's rebound during        the shooting time.

The invention, which will be described, is referred to the creation ofan absorption—reduction magnetomechanical system of this axial force,which generates the recoil and which is based, one the one hand, on amagnet's (M) presence, which in cooperation with successive recoilsprings of the same or different diameter, with spirals or metalcutting, the acceleration and the deceleration of the slide'sretrogression in a gun, and on the other hand, through the mechanicalonly method, where one of the (successive) springs (having the sameaxial or another axial arrangement level) and (in succession with theabove-mentioned) participates in the movements' participation with timedelay, since its edges do not adjoin from the beginning to referencepoints upon the gun, but after the firing of each bullet in it. Theresult of all this function is the biggest possible control of the gun'srecoil.

BRIEF PRESENTATION OF FIGS. -1- AND -2- OF THE SUGGESTIVE SOLUTION

In FIG. -1- the developmental force of recoil—retrogressionabsorption—reduction mechanism arrangement is presented and is consistedof the cylinder's (1) body of which the spring (5) is positionedexternally, which cylinder is divided in two chambers, (A) and (B)through one contraction (Y), in which chambers, on the one hand, the pin(4) is inserted, and on the other hand, the springs (2) and (3), whichare secured, on the one hand, from the transversal cover (6), and on theother hand, from the washer—separator (7), which is embodied with thepin (4). The separator (7) is the one pin's (4) edge through which edge,the pin is grounded with the gun's fixed section and in extent with itshandle. The left pin's expansion (4) with the indication (P) penetratesthe transversal cover (6), comes to the slide area (K) and is formed ona magnet's (M) support base, which is secured with the component (E) andof which the magnetic lines, on the one hand, pull the slide and on theother hand the cylinder (1) with a parallel course towards the exit ofthe gun's gun-barrel R), while in FIG. -2- the magnet (M) is supportedon the base (9) because from the pin (4) the indication (P) issubtracted.

FIG. -1- Arrangement Analysis.

The big exterior diameter of the cylinder's (1) body is coming throughthe spring (5) of which the one edge is based on the cylinder's wall(T), which is configured in a bigger diameter, and the other edge of itis based on the gun's slide (K). The pin (4) every now and then bringsthe separators (7) and (8), which designate, on the one hand, its axialcourse, and on the other hand, they operate as the recoil springs'points of reference. The spring (2), entering the chamber (A) throughthe one edge, steps on the bulkhead's (Y) one surface and through theother edge to the pin's (4) separator (7). During their installation,the springs (5) and (2) are under the minimum charge. The spring (3) ispositioned in chamber (B) and is secured by the cover (6), but since itis lower than the chamber's height, during its initial positioning itisn't strained not even from the minimum initial charge, so the spring's(3) edges are in a distance, on the one hand, from the cover's (6)internal surface, and on the other hand, from the separator's (8)surface.

The System's Operation During the Bullet's Firing Time.

A time fraction before the firing, the springs (2) and (5) have theminimum charge in contrast with the spring (3), which is located in thechamber (B) under zero charge, since its edges do not osculate at anyreference point, while the slide's (K) front views, on the one hand,towards the exit of the gun-barrel, and on the other hand, of thecylinder (1), are osculated with the magnet's (M) surface.

During the bullet's firing time, the deployed gases' pressure reachesthe point, which is designated as critical for the magnet's pull overthe slide only, where the slide (independent from the cylinder) placesitself in motion with increased momentum, cuts the magnetic lines andstarts to retrogress, pushing the spring (5), which acts over thecylinder (1). Nevertheless, on the one hand, the spring (2) because ofbigger resistance, and on the other hand, because of the magnet'spulling force, do not permit the cylinder (1) to drift immediately toregression. So, the slide continues its regression until it bangs to thecylinder's point (S), which is configured in a bigger diameter.

On point (S), where the slide is met with the cylinder, any furtherspring's (5) compressing is interrupted, and as the bullet's gasescontinue to increase their pressure, they reach the point, where it isdesignated again as critical for the magnet's pull (this time) over thecylinder, where the slide's continuous regression sets also the cylinder(1) to regression, which diverges from the magnet. During this phase,the slide (K) after the spring (5) and the cylinder (1), regress as auniform body, compressing the spring (2). Taking into account that thepin (4) is not moving towards any direction, and since the cylinder (1)increasingly regresses compressing also the spring (2), through thecover (6) increasingly minimizes the freedom degree the spring (3) hasbetween the cover (6) and the separator (8). Until this time point,where the expansion takes place from the bullet's firing, which actsover the slide, only two springs take place as a retroaction system,since they are positioned successively, which means the (5) and the (2)operate as one. As long as the slide's regression continues with thedecelerated movement therefore the cylinder's (1) also, and while thespring (2) almost approaches by the 3/5 of the completion of itscompressing, then the spring (3) acquires reference points tangential,on the one hand, with the cover (6), and on the other hand, with theseparator (8). The increasingly slide's and cylinder's deceleratedmovement meets the spring (3) in total inertia, hence this absorbsinstantaneously the most of the rest of the slide's energy, before thespring manages to enter to the absolute procedure of compressing. Theresult is to have an on the spot interruption of any further slide'sregression and since the gases' expansion has comes upon from thefiring, the chamber -slide- system begins to move in opposite direction,which means forwardly with the maximum acceleration. This is caused ofthe spring's (3) inertia condition, which acts as percussive mechanismagainst the slide with momentum and direction opposite the slide'sregression, minimizing the recoil tension and time. The instantaneousdelay, which comes from the magnet's presence, causes the gases' maximumexpansion and gives bigger initial speed to the bullet, with theconsequence of its trajectory's increase. It has also positive influenceto the slide's axial displacements, since its tempering time to theinitial position is reduced. Except the magnet's (M) pre-mentionedsupport method where through the pin's (4) body expansion, whichpenetrates the cover (6) and enters the slide's area, another magnet'ssupport method is through the use of different stand-by points in thefixed places (frame), where all the guns have. In this case, through arespective formed base for each type of a gun, like the base (9) of FIG.-2-, which is embodied either with the fixed gun-barrel (K) or with anyother gun's fixed point on which the magnet (M) is positioned, whichpulls the cylinder (1) and the slide. In this case, the pin (4) doesn'tneed to be extended till the magnet, as this is depicted in FIG. -2-.

The system can function also without a magnet with only a mechanicalway, with the assumption that there will not be imparted increased forceto the bullet, therefore any bigger trajectory. With the properconfiguration of the invention's main attachments, like the cylinder'sshape, the springs' force and the dimensions (while the spring (3)maintains the specifications of its freedom degree) and without theinvention being expanded beyond its limits, the system will be possibleto adapt itself to any gun type.

1. A magnetomechanical system of the caused recoil's reduction from a gun's bullet firing, which consists from successive recoil springs in cooperation with one cylinder and with one mechanism, which brings a magnet, and is comprised from one spring (5) of which the one edge is osculated with the slide K) and its other edge with the wall (T) in the transversal cylinder's (1) body exterior diameter, which cylinder, through a contraction (Y), is separated into two chambers, the (A) and the (B), where in (A), the spring (2) is positioned and through chamber (B) the pin (4) is passing through as it comes through chamber (A) also in the right edge of which pin, the separator (7) is embodied, which, on the one hand, holds the spring (2), and on the other hand, it consists a part of the fixed gun's frame, while intermediately of its length, the pin (4) brings the separator (8), which is interrupted from the diaphragm (Y), and from the fact that in chamber (B) the spring (3) is positioned with easiness, which is smaller in height from the chamber's (B) height, the entrance of which is secured from the transversal cover (6), through which the pin's (4) extension (P) is coming through on the edge of which the magnet (M) is embodied and is secured with the component (E), or through the use of one base (9), which is embodied on a fixed point of the gun (frame) or on other pre-existed support points under the gun-barrel, which are located on the gun's fixed parts and are destined for the support of various auxiliary components, and on which base (9) the magnet (M) is fixed without using the pin's (4) extension (P), and from the fact that the magnet's destination is to act unstoppable pull, on the one hand, to the slide (K), and on the other hand, to the cylinder (1) with momentum and direction towards the axis of their course towards the gun-barrel's exit and hence opposite towards their retrogression, and from the fact that during the bullet's firing time, the pressure of the developed gases reaches the point, where it is appointed as critical for the pulling ability the magnet (M) has, in order to hold the slide (K) and the chamber (1), causing to them the instantaneous expected delay before their departure (according to the upper priority degree), and from the fact that through the upper instantaneous delay through which the maximum expansion of gases is caused, bigger initial speed to the bullet is given, resulting to its trajectory increase, and from the fact that the spring (3) through its freedom degree on either side of its reference points in chamber (B), operates as an inertia system and acts as percussive mechanism of instantaneous absorption of the rest of the slide's (K) energy, decelerating any of its further retrogression as the most of the energy, which the slide was carrying, was absorbed from the progressive compression of the two previous springs (5) and (2), and from the fact that this mechanism's final form is capable to differ in its component's shape, to the force of its springs and to their number in order to be adapted to any different gun type.
